1.spring configuration file
The code copy is as follows:
<bean id="configproperties"
>
<property name="location" value="classpath:jdbc.properties"/>
</bean>
2. Read the attribute method
The code copy is as follows:
ApplicationContext c=new ClassPathXmlApplicationContext("classpath:applicationContext-datasource.xml");
Properties p=(Properties)c.getBean("configproperties");
System.out.println(p.getProperty("jdbcOrcale.driverClassName"));
Another friend provides a way to read the spring configuration file, please share it.
Direct reading method:
The code copy is as follows:
public void test() throws IOException
{
Resource resource = ApplicationContextFactory.getApplicationContext().getResource("classpath:com/springdemo/resource/test.txt");
File file = resource.getFile();
byte[] buffer =new byte[(int) file.length()];
FileInputStream is =new FileInputStream(file);
is.read(buffer, 0, buffer.length);
is.close();
String str = new String(buffer);
System.out.println(str);
}
Read through spring configuration:
The code copy is as follows:
package com.springdemo.resource;
import org.springframework.core.io.Resource;
public class ResourceBean {
private Resource resource;
public Resource getResource() {
return resource;
}
public void setResource(Resource resource) {
this.resource = resource;
}
}
Spring bean configuration:
The code copy is as follows:
<!-- You can directly assign a file path to the resource attribute of Resource type. Spring will automatically convert it to the corresponding Resource according to the path -->
<bean id="resourceBean" >
<property name="resource" value="classpath:/com/springdemo/resource/test.txt" ></property>
</bean>
